linux/centos6.5下编译安装python2.7

①安装python2.7
解压python源码包
tar -xf Python-2.7.6.tar.xz


进入软件包目录
cd Python-2.7.6


添加配置项
./configure --prefix=/usr/local/python27


编译
make


报错

Python build finished, but the necessary bits to build these modules were not found:
_bsddb             _sqlite3           _ssl            
_tkinter           bsddb185           bz2             
dbm                dl                 gdbm            
imageop            sunaudiodev                        
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

centos安装盘中有相关的依赖包安装即可（readline）
方法：
将centos6.5的光盘挂载在/mnt/cdrom目录下
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cd /mnt/cdrom/Packages/


提示缺少readline-devel包，安装readline-devel包的时候提示依赖ncurses-devel
 rpm -ivh ncurses-devel-5.7-3.20090208.el6.x86_64.rpm


 rpm -ivh readline-devel-6.0-4.el6.x86_64.rpm




删除相关的目录重新配置并编译
rm -rf /usr/local/python27


./configure --prefix=/usr/local/python27


make


make install


后面继续报缺少依赖包直接忽略


②安装ipython1.2.1
tar -xf ipython-1.2.1.tar.gz


cd ipython-1.2.1


使用python27对ipython进行编译
/usr/local/python27/bin/python2.7 setup.py build
编译成功执行安装
/usr/local/python27/bin/python2.7 setup.py install


如果安装成功则在/usr/local/python27/bin目录下有一个ipython文件
ls /usr/local/python27/bin/


######################
将python和ipython链接到bin目录下，方便调用(直接输入python和ipython命令即可)
ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27


ln -sv /usr/local/python27/bin/ipython /usr/bin/
